 This is a tiny but **fully loaded** printf, sprintf and snprintf implementation.  

 Primarily designed for usage in embedded systems, where printf is not available due to memory issues or in avoidance of linking against libc.  

-Using the standard libc printf may pull **a lot** of unwanted library stuff and can bloat code size about 20k. In this case the following implementation can be used.  

-Absolutely **NO dependencies** are required, printf.cpp brings all necessary routines, even its own fast `ftoa` conversion.

+Using the standard libc printf may pull **a lot** of unwanted library stuff and can bloat code size about 20k or is not 100% thread safe. In this cases the following implementation can be used.  

+Absolutely **NO dependencies** are required, *printf.c* brings all necessary routines, even its own fast `ftoa`, `ntoa` conversion.

 

-If memory footprint is really a critical issue, floating point support can be turned off via the `PRINTF_FLOAT_SUPPORT` compiler switch.

-When using printf (instead of sprintf) you have to provide your own `_putchar()` low level function as console output.

+If memory footprint is really a critical issue, floating point and 'long long' support and can be turned off via the `PRINTF_FLOAT_SUPPORT` and `PRINTF_LONG_LONG_SUPPORT` compiler switches.

+When using printf (instead of sprintf) you have to provide your own `_putchar()` low level function as console/serial output.
